bolt elongation meter
▶ The FIRST cost-effective ultrasonic solution available on the market.
▶ EFFECTIVELY monitor your bolts during periodic shutdowns over the service life of the fastener.
▶ VISUALLY compare the unloaded to the loaded waveform
▶ MEASUREMENT QUANTITIES Time (nanoseconds), Elongation, Load, Stress, and %Strain.
▶ DISPLAY OPTIONS — RF, Rectified, Large Digits with Limits Bar.
▶ DISPLAY RESOLUTION 1/8 inch VGA 240 x 160 pixels.
▶ STORES 8000 readings and waveforms in multiple groups.
▶ BUILT-IN linear regression or vector for optimizing load measurements.
▶ AUTO SET feature automatically opti- mizes detection and adjusts display.
▶ HI/LO ALARM tolerance limits work in conjunction with the data port and external pump shut-off device

Since the bolt has elasticity, the length of the bolt increases as the clamping force increases.
Since the optimal torque (Torqur) is 80% just before the bolt is damaged,
No torque should be applied, and accurate control of the tightening force will allow the bolt to be used at greater strength.
